From the manual.

The balance range for the Ultimate is 1-1/2 to 1/2 from the leading edge of the rear cabane-without fuel. Start at 1-1/2 then slowly move back in small steps.


I was confused at first when I read the manual. As I said I am 1inch from the leading edge of the rear cabane strut(Rear attachment point) I will measure the total from the leading edge of the wing to the balance point that I am currently set at.
